Classes
class	thorin::plug::clos::ClosLit
	Wrapper around a Def that can be used to match closures (see isa_clos_lit). More...

Functions
Closures
ClosLit	thorin::plug::clos::isa_clos_lit (Ref def, bool fn_isa_lam=true)
	Tries to match a closure literal.
Ref	thorin::plug::clos::clos_pack (Ref env, Ref fn, Ref ct=nullptr)
	Pack a typed closure. This assumes that fn expects the environment as its Clos_Env_Paramth argument.
std::tuple< Ref, Ref, Ref >	thorin::plug::clos::clos_unpack (Ref c)
	Deconstruct a closure into (env_type, function, env).
Ref	thorin::plug::clos::clos_apply (Ref closure, Ref args)
	Apply a closure to arguments.
Ref	thorin::plug::clos::apply_closure (Ref closure, Defs args)
template<class N >
std::tuple< const Extract *, N * >	thorin::plug::clos::ca_isa_var (Ref def)
	Checks is def is the variable of a mut of type N.
Closure Types
const Sigma *	thorin::plug::clos::isa_clos_type (Ref def)
	Returns def if def is a closure and nullptr otherwise.
Sigma *	thorin::plug::clos::clos_type (const Pi *pi)
	Creates a typed closure type from pi.
const Pi *	thorin::plug::clos::clos_type_to_pi (Ref ct, Ref new_env_type=nullptr)
	Convert a closure type to a Pi, where the environment type has been removed or replaced by new_env_type (if new_env_type != nullptr)

Closure Environment
tup_or_sig should generally be a Tuple, Sigma or Var.
static constexpr size_t	thorin::plug::clos::Clos_Env_Param = 1_u64
	Describes where the environment is placed in the argument list.
size_t	thorin::plug::clos::shift_env (size_t i)
size_t	thorin::plug::clos::skip_env (size_t i)
Ref	thorin::plug::clos::ctype (World &w, Defs doms, Ref env_type=nullptr)
Ref	thorin::plug::clos::clos_insert_env (size_t i, Ref env, std::function< Ref(size_t)> f)
Ref	thorin::plug::clos::clos_insert_env (size_t i, Ref env, Ref a)
Ref	thorin::plug::clos::clos_insert_env (Ref env, Ref tup_or_sig)
Ref	thorin::plug::clos::clos_remove_env (size_t i, std::function< Ref(size_t)> f)
Ref	thorin::plug::clos::clos_remove_env (size_t i, Ref def)
Ref	thorin::plug::clos::clos_remove_env (Ref tup_or_sig)
Ref	thorin::plug::clos::clos_sub_env (Ref tup_or_sig, Ref new_env)
